fs/procfs/fs_procfsproc: Extended the process ID ProcFS output to show per-thread maximum time for pre-emption disabled and maximum time within a critical section.
sched/sched/sched_critmonitor.c: Adds data collection logic in support of monitoring critical sections and pre-emption state.
The user of this invalidation are mmcsd_sdio currently. The mmcsd_sdio driver makes calls for dcache invalidation through the chip specific architecture function SDIO_DMARECVSETUP(). I changed the arch/arm/stm32f7 chips to use arch_invalidate_dcache_by_addr() instead of arch_invalidate_dcache().
This commit includes additional changes to mmcsd_sdio.c. I created SDIO_DMADELYDINVLDT() (DMA delayed invalidate) to invalidate store-into mode dcaches after the DMA transfer. I have been using SDIO_DMADELYDINVLDT() for several weeks now and it has fixed the problems that I previously reported regarding non-cache aligned buffer invalidation errors (for my store-through dcache). However, it does not permit use of unaligned DMA buffers for store-into mode dcaches.
SDIO_DMADELYDINVLDT() is a NoOp unless the chip specific Kconfig file selects CONFIG_ARCH_HAVE_SDIO_DELAYED_INVLDT. I have modified all the stm32f7 chips to select it.
The MLD implementation did not follow the RFC correctly when it is the Querier. The Querier should use a general query and get query messages from all members of all groups. This would be driven by a single timer per sub-nset since all groups are queried at once. Instead, the design used a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.
Similary, the MLDv1 compatibility timer should be a single, separate timer, not a per-group timer.
net/mld: Group may be NULL when sending a general query
include/nuttx/clock.h: Fix uptime wrong if DEBUG_FEATURES and SCHED_TICKLESS enabled
include/nuttx/arch.h: fix CONFIG_ARCH_INTERRUPTSTACK not defined warning
include/nuttx/audio/audio_i2s.h: Fix warning: struct i2s_dev_s declared inside parameter list
RNDIS composite support
* NuttX usb/composite.h: Forward-declare composite_devdesc_s.
This avoids "error: conflicting types for 'composite_initialize'"
on some versions of GCC. Because of the cross-inclusion between
usbdev.h and composite.h, the full declaration is not always
available.
* NuttX: USB Composite driver: Fix strid comparison
The last string ID used by composite driver is 4, and
the number of IDs used is 5 (0..4). The comparison
strid <= COMPOSITE_NSTRIDS caused composite driver to
reply with -EINVAL for id 5, even though it should be
available for subdevices to use.
* NuttX: RNDIS USB driver: Add support for composite configuration.

These Microsoft-only descriptors help in loading the correct driver on Windows.
They are especially helpful to give libusb access to a custom device without
having to manually configure/install WinUSB driver.
With this change DFU interface works automatically on
Windows 10 with dfu-util 0.9 and libusb 1.0.22. On Windows 7
it still appears to need driver installation.
1. Move exepath_*() related code to libc/misc
1. Rename exepath_ to envpath_
2. Rename BINFMT_EXEPATH to LIB_ENVPATH
libs/libc/modlib: Add pre module library symbol table support
net/mld: Fix a couple of places where I forgot to unlock the network in the previous commit.
net/mld: Implement 'Other Querier Present Timer'. This timer is used to revert to Querier mode if there is no other querier on the network. Also, fix some naming: The Done message is not just Version 1 but is used with Version 2 as well.
net/igmp: Back out some blind, backported improvements to IGMP from MLD. There are too many subtle differences in the protocols for this to be safe.
net/mld: Checksum calculation needs to know the full size of the IPv6 header, including the size of the extension headers. The payload size in the IPv64 header must include the extension headers (not considered part of the header in this case). Fixes a few additional errors in size, endian-ness and checksum calculations. Wireshark now reports the the outgoing Report has a good checksum.
net/mld/mld_query.c: Add a cast to assure that the left shift does not overflow.
